Metal plate double-curved surface processing technology and equipment

Abstract

The invention discloses a metal plate double-curved-surface processing technology and metal plate double-curved-surface processing equipment. The technology comprises the following steps of rolling a metal plate to be processed by using a triaxial roll bending machine, and adjusting the distance among three rollers to obtain different unidirectional curvatures, wherein convex and concave shaft sleeves are sleeved on three rollers of the roll bending machine; and allowing the metal plate to be processed to pass through the roll bending machine sleeved with convex and concave shaft sleeves to obtain a double-curved-surface plate which has a required shape. In the technology, the shaft sleeves are coated by a strip, the axial curvatures of the shaft sleeves are adjusted, and the resilience capacity of the metal plate is adjusted in a matched way. The double-curved-surface roll bending machine is provided with three rollers and is sleeved with the convex and concave shaft sleeves of which the curvatures are matched. The double-curved-surface processing technology and the metal plate double-curved-surface processing equipment have the ingenious conception, so that the tradition that the roll bending machine can only finish the roll bending production of a single-curved-surface plate is changed; therefore, double-curved-surface one-time rolling forming of the metal plate is efficiently and conveniently finished, the resilience capacity can be adjusted easily and conveniently, the accuracy is high, the production efficiency is greatly improved, and the production cost is reduced.

Description

technical field

[0001] The invention relates to a metal plate processing technology and its processing equipment, in particular to a metal plate hyperbolic processing technology and its processing equipment. Background technique

[0002] At present, the curved surface processing of aluminum alloy plates and other metal plates with a thickness between 1-4mm generally adopts the three-axis roll bending machine roll bending method, which has high efficiency and smooth and clean products. The effect quality is very good, but only single parts can be processed.

[0003] For the processing of hyperbolic parts, the following processes are commonly used in the automotive and aviation industries:

[0004] 1. Stamping method, there are upper and lower dies, and the metal plate is placed between the upper and lower dies. Generally, it is impacted by a drop press or a large punch. The efficiency is good and the quality is good, but the upper and lower dies are quite expensive, suitable...
